RUNNING-GEAR FOR MINE-CARS.

Original application filed November 30, 1907, Serial No. 404,560. Divided and this application filed January 21,1908;

-- Serial No. 411,969.

To all whom it may concern:

Be it known that we, JOHN M. PHILLIPS United States, residing at Garrick, in the county of Allegheny and State of'Pennsylvania, have invented certain new and useful Improvements in Running-Gear. for Mine- Cars, of which the following is 'a specification.

This application is a'division .of application No. 404,560, filed Nov. 30, 1907.

This invention has relation to running gears for mine cars and relates in particular.

to thewheels and axles of running gears in which the wheel is Confined in position on the axle by means of a linch pin.

- the wheel. In order to obviate this uneven is no escape for oil" at the rout of the wheel,

Wear it is necessary to supply lubricating oil more freely to the rear end of the bore than to the front end of the same, and this has been accomplished by closing thefront end of the bore, as by a cap made integral with the wheel or an attached ca so that, as there all the waste oil escaping from the oil cavity of the wheel will flow between the inner end of the bore andtheaxle, thereby keeping this portion of the bore liberally lubricated.

' The cap wheels above referred to,. while they have some goodfe'atures, the principle one of whic has been indicated above, are objected to y some operators for the reason that the linch pin whlch confines the wheel ,on the axle is concealed fromyiew, being usually arranged within the cap or at the back of the. wheel, and is liable to become worn outor broken .without attracting'at tention and to cause a serious wreck. this reason the wheel'in general use at coal minesisone with a straigh. "JOIB having an axle of uniform diameter extending through the bore and a linch pin on the outer side. df the wheel and, while theoil may escape at the front of the wheel, this form is preferred V to. the cap wheel, as the linchpin isplainly in sight and can be readily replaced if worn or ing 22 being arranged in a groove 23 formed broken. I I

Our invention has for its ob ect the provision of a wheel and axle which will possess and axle of uniform diameter and the linch It has been found in practice that the bore The axle, designated 11, is formed For pin on the outside of the wheel, and also prosscss other advantageous features, while ee from the objectionable features'of both.

ameter to form a stub-axle to fit the central 0 ening in the cap, the reduced portion of t e axle being of su'fiicient length to protrude through the opening in the cap and beyond the outer face of the cap and pierced for the .receptionof a suitable "linch in or similar device to confine the wheel on t e axle.

In the accompanying drawings: Figure-.1 is a vertical transverse sectional view of a wheel and axle constructed according to our invention and as applied to an axle 'th an axle box;- Fig. 2 1s a top plan view of the axle shown in Fig. 1.

The wheel shown in the drawing and embodying our improved construction is ofthe type known as a self-oiling wheel andis a single piece of cast metal com rising the rim 1 the s okes 2 and the hub 3, iihe latter bein forms with an oil chamber 4, having-an oi inlet 5 controlled by a spring pressedvalve 6. An opening 7 extends'from the oil chamberl l to the central bore or eye 8 of' the hub and.

serves to permit assage of theoil' from the chamber 4 to the' ore or eye. The hub 3 is formed with an integral cap -9 on, its outer side and this ca is formed'with a centrally locat dhole 10 or the reception of the end of the axle as. will be presently described.

lindrical portion 12 that fits snu ly in the boreor eye 8 of the'hub and the end 13 of the axleis reduced in diameter to such size that it will fit'the hole in the center of cap '9. The end 13 of the axle is ierced at 14 to receive a linch pin' 15 Whic wheclon the axle and a washer 16 is fitted on the end 13 of the axle between the linch pin and the end of the hub. The hub of the wheel. is formed with a rearwardly extending sleeve 19 and an axle box 20 is carried bv the car and is formed with a socket21 into which the sleeve 19extends, a ring of fibrous packin the wall of the socket andserving to preventthe passage of dust at this point. ;A loose was er 24 is interposed betweenthe end of the sleeve 19 and the bottom of the socket 21 to reduce friction'and theaxlein serves to confine the with a cythe rear of this washer is square and fits in a square hole or socket in the axle box, the

axle being held stationary and the wheel turning on the axle. The reduced end of the axle which passes through the cap on the front of the wheel joins the cylindrical portion 12 by a shoulder 25 that bears against the inner surface of the cap and this shoulder divides with the sleeve 19 the end thrust and wear so that the Wheel and axle will run a long time Without Wearing enough to decrease the gage of the car.

We claim:

In running gear for mine cars, a Wheel having a chambered lubricating hub, with an axle bore having a diminished outer end ssaesa piercing the face of the hub, the latter being formed with an integral cap through which i said bore extends, and said hub having a cyi lindrical sleeve projecting from its inner face, through which said axle also extends, in combination with an axle-passing through the hub, and a box in which the said hub sleeve rotates.

In testimony whereoffive affix our signa- 25 tures, in presence of two Witnesses. JOHN M. PHILLIPS. ROBERT F. PHILLIPS.
